CRITICAL: sole npm publisher + >10M/wk

postcss has a single npm publisher with 222M weekly downloads. This is the exact attack profile that enabled the axios compromise (March 2026) and the LiteLLM supply chain attack. A stolen credential gives an attacker publish access to a package running on millions of machines. GitHub contributors (35) don't have npm publish rights — only the publisher does.

What this score measures

The Commit trust score measures behavioral commitment — signals that are hard to fake. Unlike stars, READMEs, or download counts, these signals capture how a package is actually maintained.

Longevity — how long the package has been published and actively maintained
Publisher depth — number of people with npm publish access (distinct from GitHub contributors)
Release consistency — regular releases signal active oversight
Download trend — growing, stable, or declining adoption
GitHub backing — contributor depth and OpenSSF Scorecard process security
